Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12012, here are decompositions:
- 5 + 12007 = 12012
- 31 + 11981 = 12012
- 41 + 11971 = 12012
- 43 + 11969 = 12012
- 53 + 11959 = 12012
- 59 + 11953 = 12012
- 71 + 11941 = 12012
- 73 + 11939 = 12012
Showing the first eight; more decompositions exist.
